Cold temperature grinding fluid
Wondering if there is a grinding fluid that is suitable to use in below freezing temperatures? I have a crankshaft grinder as well as a large surface grinder that I would like to store in an unheated shop. The plan is to turn on the heat on the days when I will be using this equipment. There may...- Dave123

Welding connecting rods
The bore and stroke of the Chevrolet crank is the same as the T 3 3/4”B - 4.00 “?stroke. The difference is the size of the crank . The Model T weighs in at 16 lbs while the Chevy crank is 25 lbs. The model T engine was notorious for breaking crankshafts. Neither of these cranks are counter balanced -

Welding connecting rods
Thanks guys, all good advice, this engine is not going see any high rpm’s. With the stock T gearing 50 mph is only 2000 rpm,….fast enough for me ! -

Welding connecting rods
Milland, I know the chev rods are 7.440” in length which is .437” longer than the T rod, pin dia on the Chevy is .85” the T is .75” dia. Sorry but I do not have a Chevy piston on hand to measure the distance from the pin to the piston top -

Welding connecting rods
Looking for someone out there that has experience with shortening and welding connecting rods. I understand this has been done for years, with varying success. On this project I am installing a 28 chev crankshaft into a model T. The modifications to the crankshaft front end and rear flange are... -

shrink fitting a crankshaft flange
Ross , Are you suggesting the taper with the flange be machined from a solid piece, with the taper being longer that the flange ( on the examples I have seen the flange is .750" wide) if I understand correctly the taper could become part of the crankshaft bearing surface. (Say 2 -3" overall)... -

shrink fitting a crankshaft flange
The Chevy crank is massive compared to the T,…,25 lbs vs 16 lbs The stock T cranks are notorious for breaking. To answer your question , yes you can buy a Scat crank for $1650.00 Which would be simpler but A used Chevy crank in this case was free. I have the required machining tools including a... -

shrink fitting a crankshaft flange
Thanks Ross, I do not have the Chevy crank at the shop quite yet, will post a picture or two likely next week. Due to the lack of room available, the maximum width of the flange can only be about 3/4", even this means having to shorten the rear main bearing (babbit) in the block by 1/2" Dave -

shrink fitting a crankshaft flange
Honestly I’m not sure of the Chevy crankshaft material. Making a new flywheel would be a big job as the magnets for the magneto are attached along with the pins for the planetary gears -

shrink fitting a crankshaft flange
I am looking at adapting a 4 cylinder Chevy crankshaft into a Ford model T engine. This is not that rare of a modification to a model T, however including some basic machining to the Chevy crankshaft, it involves adapting a Ford style flange to the rear of the crank to accept the Ford flywheel... -
