Frequently Asked Questions
Find answers to the most common questions about Granberg’s products and services.
What chainsaw engine size do I need for an Alaskan Chainsaw Mill?
The ideal chainsaw depends on your mill size and intended use. For occasional or smaller log milling, a 70cc chainsaw provides adequate power. For regular use with larger logs (over 20″ diameter) or hardwood species, consider 90cc or larger. More displacement means faster cutting, less strain on the engine, and better performance in demanding conditions.
Recommended Products:
- 24″ Alaskan MKIV Mill (G778-24) – For 60cc+ chainsaws
- 36″ Alaskan MKIV Mill (G778-36) – For 70-90cc+ chainsaws (bigger is better)
- 48″ Alaskan MKIV Mill (G778-48) – For 90cc+ chainsaws
- 60″ Alaskan MKIV Mill (G778-60) – For 120cc+ chainsaws
How do I choose the right bar length for my mill?
In general, the mills are matched to bar length. So a 36” bar and 36” mill go together. However, you lose six inches off a single end bar when you mount the mill, so that particular combination will get you a cutting width of 30”. If you need to cut 36”, you would use a 48” mill and 42” bar.
If using a double ended bar, such as what comes with the “C2/C3” package mills, you can expect to have a cutting width about 4 inches less than the overall mill size (so 32” cutting on a 36” mill)
Recommended Products:
- 36″ Mill Bar & Chain Combo Pack – Comes with Mill, Bar and Chain (30-inch cutting capacity)
- 36″ C2 Complete Package – Everything needed for medium-scale milling (32- inch cutting capacity)
- 48″ C2 Complete Package – Professional-grade large mill setup (44” cutting capacity)
Should I use a different chain for milling?
Yes, use a Granberg ripping chain specifically designed for milling operations. Unlike standard crosscut chains that cut across the grain, ripping chains have a more aggressive tooth angle (typically 10° vs 30°) to cut efficiently along the wood grain. This results in smoother cuts, less tear-out, and reduced strain on your equipment. Granberg ripping chain has an additional modification that will increase your cutting speed by about 30% when compared to other brands of ripping chain.
Recommended Products:
- Granberg Pre-Cut Ripping Chain – Professionally optimized for chainsaw milling
Can I use any chainsaw brand with an Alaskan Mill?
Most professional-grade chainsaws can be used with Granberg Alaskan Mills. However, ensure your chainsaw has sufficient power and can handle extended operation under load. Different brands of chain saws also take different styles of bar mount, so check the product description in the info section of the product page to make sure your saw is compatible or if it needs an adapter.
Recommended Products:
- Alaskan MKIV Mills 24″-84″ – Fit all chainsaw makes and models
- Complete Alaskan Mill C2/C3 Packages – Include universal bar mount adapters
What other factors affect milling performance?
Beyond chainsaw power, chain sharpness (critical for clean cuts), proper chain tension, adequate bar oil flow, and your feeding technique can affect your milling experience. Environmental factors like wood moisture content (logs that have been down for a while will be seasoned and harder to cut, especially hardwoods. Temperature, and log species also significantly impact cutting efficiency and finish quality. For best results, it is recommended to always remove bark before milling.
Recommended Products:
- G1012XT Precision Grinder – 12V portable chain sharpener for optimal performance
- G801A Auxiliary Oiler Kit – Enhanced lubrication for bars over 42″
How do I maintain my equipment for milling?
Regular maintenance is essential for safe, efficient milling. Regularly check fittings, as vibration can cause some nuts to loosen. Make sure not to overtighten. Keep chains sharp, maintain proper chain tension, ensure adequate lubrication, clean air filters frequently, and inspect the mill for damage or deformity. Replace worn components promptly to maintain cut quality and safety.
Recommended Products:
- G1012XT Precision Grinder – Professional chain sharpening system
- G801A Auxiliary Oiler Kit – Extends bar and chain life through superior lubrication
How do I ensure a good first cut?
A level, straight first cut is essential for quality lumber. Use a guide system to ensure accuracy and prevent the mill from producing uneven slabs. Make sure any first guide is properly leveled and well secured to the log.
Recommended Products:
- G1010 EZ-Rail System (10ft) – Aircraft-grade aluminum rails for perfect first cuts
- G1085 EZ-Rail System (5ft) – Compact version for smaller projects
- G850 Slabbing Rail Bracket Set – Budget-friendly option using customer-provided 2x4s
Complete Starter Solutions:
- The Alaskan MKIV Mill C2/C3 packages contain everything you need to get started milling. They come with an Alaskan Mil, double-end bar, oiler kit, helper handle, first cut guide & chain sharpener.
- The Homeowner and Backcountry bundles are a good option if you already have a bar that suits your needs. (Please note that laminate bars are not compatible with the G777 and G555B Mills)
- Mill, Bar & Chain Combo Packs are ideal if you need all three. These packs include a single-end bar, matching chain, and mill—designed to work together as a complete setup.
