canada goose Posted June 24, 2016 Share Posted June 24, 2016 Would anyone have an opinion whether a 3/4 horse motor would be adequate for a Ray Clontz tire hammer . I can get one free but I don't want spend time adapting it if it's too small . Quote Link to comment Share on other sites More sharing options...
eseemann Posted June 24, 2016 Share Posted June 24, 2016 How large a ram are you thinking about using? Quote Link to comment Share on other sites More sharing options...
duckcreekforge Posted June 24, 2016 Share Posted June 24, 2016 I have had a large part in building 8 tire hammers. The blueprint is for 1 hp., which is fine, a 1 1/2 hp is available new with the same 7/8 shaft. It is the same physical size and frame. I would lean towards that. My two hammers have 1 hp motors, which I bought used at the flea market $15 - $30 each. Make sure the're 1725 rpm. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted June 24, 2016 Share Posted June 24, 2016 I've picked up cheap motors before from places that do motor work. Someone will bring one in and then balk at paying the price when they rebuild it and abandon it there and they will try to get their cost out of it.

basher Posted June 25, 2016 Share Posted June 25, 2016 I have never made a tire hammer but have owned and run a lot of mechanical hammers. they definatly run better with bigger motors, get the biggest you can run easily. Quote Link to comment Share on other sites More sharing options...
arftist Posted June 25, 2016 Share Posted June 25, 2016 Horsepower requirement depends upon tup weight; Figure 1hp for 25 pounds 2 for 50 3 for 100 There is a little wiggle room, for example my 75 pound hammer runs fine on 2 hp. 3/4 hp would a twenty pound hammer fine. Remember though that too much is always enough. Quote Link to comment Share on other sites More sharing options...
eseemann Posted June 25, 2016 Share Posted June 25, 2016 DuckCreekForge makes a VERY good comment about 1750 RPM. I picked up a 1 HP motor that turned out to be 3600 RPM and I will need to make sure i have the spindle to tire ratio correct so the hammer does not sound like an MG42 and/or spastic woodpecker.

canada goose Posted June 26, 2016 Author Share Posted June 26, 2016 Well it looks like 3/4 would be pushing things as the hammer weight is 50 lb. I know the clay Davis tire hammer runs just fine with 1hp . Quote Link to comment Share on other sites More sharing options...
Bo T Posted June 27, 2016 Share Posted June 27, 2016 Down here a lot of power is 15A, 110v. So 1.5 hp would be tops. If you have 220v, then you could run a more powerful motor. Quote Link to comment Share on other sites More sharing options...
Frosty Posted June 27, 2016 Share Posted June 27, 2016 My 50lb. LG runs okay with 3/4HP on a 120v through a 20a breaker. Never tripped the breaker. The book calls for a larger pully on the motor but being a little slow and wimpy means I don't make mistakes permanent quite so quickly. Frosty The Lucky.
