G0704 belt drive
I got my Grizzly G! These mills are commonly referred to as BF20's with L designating a long table with extra X axis travel. They've been around for years in Europe and Asia along with a few places in North America but with a less desirable MT spindle.
R8 spindles are now becoming readily available and with recent editions from Grizzly and others their popularity is booming. I've wanted one for years. Their superior design and quality construction puts the other mills to shame and often for the same or less money. The BF20 is in the same size range as an X3. There are other sizes of BF class mills from 16 to The is the approximate drilling capacity in mm's.
Use the drop down menus below for much more information. Be sure to check back for new additions as I'll update as new info and projects arise. Scroll down to see pics of my adventure and follow the blog. Update: Grizzly is expecting a shipment of these mills on Feb. Time to prepare. Noticed they posted links to a new pdf manual and parts list. Must still be working on uploading them, I get a server error but they should be available shortly. More time time check out some other builds.
These BF20's are not new, they've been available in Europe and Asia for years. Folks there have already done conversions and upgrades to them. These are some links to several I have found, plenty of food for thought for inspiration.

I purchased some XL series timing pulleys and a belt from Econobelt to work with. The driven pulley for the spindle is a 36 tooth metric bore 8mm with a 45 mm hub. That works out to be the same diameter as the G spindle, which simplifies mounting the tach wheel. The driven pulley is machined to fit over the end of the spindle in place of the tach wheel and is mounted by the same holes that held the tach wheel in place.
I'll either draw this up or post more detailed dimensions once I get a little farther. Here is what i have so far. Here are the parts that I started with. The largest one is the 36 tooth pulley. The other three are pulleys that I intend to select a drive pulley for the motor from. The black ones are 25 and 27 tooth nylon with aluminum hubs and 10mm bore, which is very close to the motor shaft size.G0704 with Bench Top Precision belt drive \u0026 1100 watt motor.
The flanged aluminum is a 25 tooth with an 8mm bore that i would need to bore out. These three views just show the un-machined pulley with the tach wheel sitting on the hub - since it is the same diameter as the top of the spindle, it will need no further machining. These views show the enlarged bore of the pulley to clear the drawbarthe recess to center the pulley on the spindle bored into the flat side of the pulleythe shortened hub, and the mounting holes drilled to match the holes in the spindle and the tach wheel.
They also show how the tach wheel and pickup will sit on the new pulley. Here are the pulley and tach wheel mounted in place on the spindle. I bored the recess that sits over the spindle to a nice snug fit so that it transfers any side force tot eh spindle directly instead of to the two 3mm socket head cap screws.
Out of time right now, so I'll post more later.Thread: Grizzly G belt drive kit. Results 1 to 1 of 1. Grizzly G belt drive kit. I bought this belt drive kit from Home Machine Shop.

The intermediate gear set that connects the motor output to the spindle are made of plastic and will break at some point. Usually at the worst of times. This kit completely replaces the two speed gear box with a two speed belt drive. Below are some more specs and features. If you are unsure please contact me.

Kemp and Hossmachine, is strictly prohibited.Fallen idols: The three Pakistani cricketers at the centre of the match fixing allegations, (left to right) Mohammad Aamer, Mohammad Asif and Salman Butt, leave Heathrow Airport for LahoreThe bowling of a wide off the first ball has long been understood in cricket circles as open to manipulation for spread betting and spot- fixing.
First ball nerves and, in this case, the need to adjust to the slope at Lord's means such a delivery is not uncommon there. But Davies, whose involvement with the ICC began soon after the setting up of the Anti-Corruption Unit, believes that in the light of the current allegations, Aamer's five-run wide should be scrutinised by the investigation, led by former policeman Sir Ronnie Flanagan. Anyone armed with certain information that the first ball would be a wide and produce five runs could make a lot of money on all those spreads.
If I was advising the Anti-Corruption Unit on their investigations, I'd be reviewing everything from ball one. That's why, if these allegations are proven, these guys should be thrown out of the game.
I don't see how you cannot impose the harshest penalty, to send a clear signal. If you don't do that you are saying that crime pays.
Warm welcome: Protesting fans awaiting the return of disgraced skipper Salman ButtThey have until Thursday to respond to the charges laid by the ICC and the indefinite suspension pending an inquiry. Prior to the start of the T20 and one-day series against Pakistan, which continues at Headingley today with England 1-0 up, the ECB made it clear they would not be happy to play against players under police investigation. But they resolved not to make further protest about the presence of Wahib or Kamran Akmal, deciding instead to get through the remaining matches as quickly and quietly as possible.
Meanwhile, England's Jonathan Trott denied he used the allegations to get under the skin of Kamran Akmal during an on-field spat in the first ODI in Durham, which caused umpire Billy Doctrove to intervene. Trott yesterday played down the incident which left Akmal furious, saying: 'I said a few words, and he was saying a few - and the umpires got in the middle of it and made a mountain out of a molehill really.

How could they be that stupid.It was easy and stress free and we had a wonderful time. Thank you for everything - it was well organised. The mobile phone was great. Thank you - it was a fantastic holiday!!. The trip was great. We took more than 2500 pics, we drove more than 3300 Km.
We met many friends on the way - most of them "Nordic people". The service provided and information received before the tour was excellent. The standard of accommodation was excellent, for me the best experience was sleeping in the national park, however every single hotel was wonderful. We had the best guide-driver we could dream of.
For us he was more than a guide. I have a deep respect and admiration for Asgeir who helped us to discover, understand and fall in love with this beautiful country. He adapted himself so kindly to our needs and tantrums. My daughter keeps talking about him. I do not exaggerate when I say he is her hero. Now everyone knows him in France and in England.
I was not expecting such high quality standard of meals. My favorite was a meal at the last restaurant where every single dish was a delight (Hotel Ranga). It was definitively the best restaurant along with the sea food bar in Reykjavik. Ask Thora for the name.
