homemade warn 8274 pneumatic freewheel

[85lux]

grabbed a cylinder, solenoid and regulator from work today.
maesured up the original freewheel lever/plate.
should be a piece of piss to make myself, no more than 2 hrs machining.
anybody else thought about doing this themselves???

Keep us updated on how you go.

[85lux]

update, the plate that holds the gear is done, the flange that bolts to the gearbox is blanked out, just need to pitch out the 4 holes around the outside then 4 holes to mount cylinder then assemble and done.

Any chance of photos.

[85lux]

photo's are difficult for me, i dont have a dig camera. will borrow one when its complete and post up.

what gear you using?

[85lux]

cylinder: festo advu-20-25-a-pa

solenoid: festo mfh 5-1/8

regulator: some SMC thing.

plate to hold gear: made from M200 tool steel

flange to bolt to gearbox: 6061 alluminium.

probably run 4mm air line.

the requered throw of the gear is near 20mm, the cylinder is 25mm so i will turn a nylon shim to limit the cylinder stroke.

sounds good

was thinking bout something for low mount winches using some festo gear

[85lux]

not familiar with low mounts, do they require a shaft to be push/pulled or rotated??? sounds like a go'er

[spazbot]

shaft needs to be rotated , was looking at using one of the swivel rotary drives under the dsr or dsm product range

I done it I had the cylinder made to my spec by SMC ($110) machined up the adaptor place and used a 2 position Parker 5 port soleniod valve and it works a treat with 2 micro buttoms/switches and a couple of relays.
